The DMT Diafold Serrated Knife Sharpener is a special use tool for sharpening serrated knives and concave surfaces. The narrow diamond coated steel cone tapers from .25" at the handle to .062" at the tip and fits most bread and tactical knives. The DiaFold handle makes use and storage comfortable.
Although it was designed for sharpening knives, in the Gramercy workshop, we love making custom scrapers, scratch beaders and cutters and the Diafold Serrated Knife Sharpener is great for that. The exceptionally narrow tip gets into tight curves that a stone can't and the diamond abrasive can cut full hard tool steel or carbide. This isn't an everyday sharpener (unless you happen to be a bread-knife maker) but it's a good sharpener, that does a job many others simply can't.
The DMT Serrated Knife Sharpener is Made in the USA.
